Hi @sabine so i played around with this over the weekend and I managed to pull it off.
Here, is a video of the implementation. Please let me know what you think 😊

Hey @oyenuga17! Thanks for the contribution! This looks very nice.

Here's a few issues:

• ESC key cannot be used to close the modal
• clicking outside the modal does not close the modal

I think that having a HTML/JS/CSS modal here is probably too complex for what is needed here. It will be much simpler to use the browser's built in confirm() method (see https://developer.mozilla.org/en-US/docs/Web/API/Window/confirm?retiredLocale=de) to obtain confirmation from the user.

Alternatively, we can update the privacy policy to list that using the dark/light mode switch will use LocalStorage to remember the user's setting.

hmm... you're right @sabine, might be hard to achieve a fully accessible modal using this my approach. I'll try the window.confirm method since that's the closest thing to what we're trying to achieve.
